THOMAS IV. HAMLIN, OF SARAWAK, CANADA.

MACHINE FOR POINTING SKEWERS.

SPECIFICATION forming part of Letters Patent No. 570,630, dated November 3, 1896.

Application filed January 22, 1896. Serial No. 576,470. (No model.)

To all whom it-rntty concern:

Be it known that I, THOMAS WALROND HAMLIN, of the township of Sarawak, in the county of Grey and Province of Ontario, Canada, have invented certain new and useful Improvements in Machines for Pointing Skewer- Blanks; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in machines for pointing skewer-blanks, and relates more particularly to the means employed for continuously feeding the skewer-blanks from the hopper to the cutter-knives; and the object of the invention is to so arrange the machine that the skewer-blanks can be fed regularly and con tinuously to the cutterknives; to so arrange the cutter-knives that the knives will, during the passage of the skewer-blanks from the hopperto the delivery-table,shave the skewerblanks from heel to point of the taper; to provide a concaved course for the skewer-blanks concentric with the cutter-heads and the invention consists, essentially, of the device hereinafter more fully set forth, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of the complete machine. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a view, partly in section, of the cutterheads and shaft. Fig. 4C is a side elevation of the cutter-heads.

Like letters of reference refer to like parts throughout the specification and drawings.

At the head of the frame A is located ahopper B to temporarilyhold the skewer-blanks, and at the bottom of the hopper B is an openin gb, through which the skewers are delivered into a vertical chute 0. Located below the hopperB are two horizontally-movable tables D D. Each of the tables D D has a concaved face E. Connected to the sides a of the frame A, in front of the tables D D, are

two cross-beams F, each of which is slotted longitudinally. Mounted on the cross-beams standards is a sleeve H, on which is loosely mounted an idler I. The idler I is opposite the table D, the concavity of which is con-, centric with the perimeter of the said idler. Secured to the outer side of the standard G is a similar sleeve H, on which is mounted an idler l, opposite the table D. The concavity of the table D is concentric with the perimeter of the idler I. J ournaled in the sleeves H H is a horizonal shaft J, the ends of which are journaled in bearings K, mounted on the top of the sides Ct. The shaft J revolves loosely in the sleeves H H. Rigidly mounted on the shaft J are two cutter-heads L L, respectively. The cutter-head L islocated contiguous to the outer side face of the idler I, while the cutter-head L is located contiguous to the outer side face of the idler I. The cutter-heads L L are rigidly mounted on and revolve with the shaft J. Each of the cutter-heads L L is provided with a series of adj ustableknives M M M M. The cutting edge of each of theknives M M M M' is arranged obliquely to the plane of the revolution of the cutter-head, the point of each of the knives being upturned, so that the knife will shave the skewer-blank from the heel to the point of the taper.

J ournaled in the sides aof the frame A in front of and below the shaft J is a shaft N, and rigidly mounted on the shaft N are two pulleys O O, which are located in alinement with the idlers I 1, respectively. Passing around the idler I and the pulley O is a rubber belt P, and passing around the idler I and pulley O is a rubber belt P. The belts P P are a distance remote from the concaved faces of the tables D D, respectively, approximately equal to the diameter of the skewerblank. J ournaled in the lower part of the foot of the machine'is a counter -shaft Q, and mounted on the shaft Q is a pulley R. Mounted on the shaft J is a pulley S on the same side of the machine as the pulley R. Passing around the pulleys R and S is a belt T. Mounted on the shaft Q is a pulley U, of a lesser diameter than the pulley R, and journaled in the head of the machine is a shaft-V.- Mounted on the shaft V is a pulley "The pulley W is of a greater diameter' thamthe pulley U, and passing around thepulleys U and W is a belt W. Mounted on -itheopp0 site end of the shaft Yissapulley-Y, of.a-

smaller diameter than the pulley WV, and

mounted on the shaft N is a pulley N, of a greater diameter than the pulley V, and passing around the pulleys V N is a belt N.

Motion is transmitted to the counter-shaft Q, and from the counter-shaft Q motion is transmitted to the shaftJ by means of the belt T. As the pulley R is of a greater diameter than the pulley S, the shaft J will revolve at a much higher rate of speed than the counter-shaft (.2. Motion ,is also transmitted from the counter-shaft Q to-the shaft V by means of the belt W. As the pulley U is of a lesser diameter than the pulley IV, the shaft V will revolve at a lower rate of speed than the shaft Q, and motion is transmitted from the shaft V to the shaft N by means of the belt N, and as the pulley V is of a lesser diameter than the pulley N the shaft N will revolve at a slower rate of speed than the shaft V. It will therefore be seen that the shaft N will revolve at a much slower rate of speed than the counter-shaft Q. The belts P P move in the direction indicated by arrows and carry the skewer-blanks down the concaved faces of the tables D D. The cutter-knives revolve in the direction indicated by arrows, that is, reverse to the belts P P, and work against the skewers while they are passing down the concaved surfaces of the table andshave the skewers from the heel to point.

To regulate the delivery of the skewerblanks from the hopper, I provide two slides X X, located one about one-quarter of aninch above the other, and entering the side of the chute slightly below the opening b at the bottom of the hopper. Mounted in bearings. Y in the head of the machine is a horizontal shaft Y, and mounted on the shaft Y are cams Y Y. Mounted on a shaft Y, journaled in the framework, are two rocking levers Z Z, operated, respectively, by the cams Y Y. The lever Z moves the slide X, while the lever Z moves the slide-X. The operation of the levers Z Z is alternate, in order that the slides X X will be alternately moved. The lever Z moves the slide X to allow of the delivery of one skewer-blank to the top of the slide X. The lever -Z then returns the slide X to arrest the delivery of the skewer-blanks until the lever Z has moved the slide X to deliver the said skewer-blank to the concaved surfaces of the table, this action being continued during the operation of the machine. By means of these slides and levers the skewer-blanks are delivered regularly and continuously to the concaved surfaces of the tables to allow of the cutter-knives shaving. Mounted on the end of the shaft Y is a pulley G, and mounted on the corresponding end of the shaft V is a pulley C, and passing around the pulleys C C is abelt c, by means of which motion is transmitted from the shaft V to the shaft Y.

As the skewer-blanks vary in diameter, it

. is necessary to provide a means for increas ing under pressure the width of the space between the concaved faces of the tables and the adjacent faces of the rubber belts. To accomplish this result, I provide the periphery of each of the idlers I I with a circular rubber cushion t. Mounted on the shaft V is a drum 2;, and journaled in the sides a of the frame A'is a drum 1), and passing around the drums I; b is a belt 1;, on which the skewers drop from the tables.

The action of the machine is as follows:

Motion is transmitted to the various parts by means of the belts and pulleys hereinbefore described. The skewer-blanks are placed in the hopper and are fed to the tables, passing down between the rubber belts P P and the concaved faces of the tables D D. During their passage down their course they are operated on bythe knives of the cutter-heads, and are afterward delivered to the belt 0', which is continually moving around the drum 2;, and are delivered from the belt into receptacles placed to receive them.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a skewer-pointing machine, the combination with the hopper of a feeding apparatus consisting of two slides one located above the other, a shaft journaled in the frame, cams mounted on the shaft, levers operated by the cams, arranged to work the slides alternately, to allow of the delivery only of one skewer-blank at a time from the hopper, skewer-supporting tables, a concaved face for each of the tables, a horizontal shaft, opposed to the tables journaled in the frame, pillow-blocks opposite the interval between the tables, sleeves supported by the pillowblocks encircling the shaft, idlers mounted on the sleeves opposed to and concentric with the concaved faces of the tables, cutter-heads mounted on the shaft on the sides of the said idlers, a second shaft, pulleys mounted on the second shaft, belts passing around the said pulleys and idlers, and means for impart ing motion to the machine, substantially as specified.

2. In a machine for pointing skewer-blanks, the combination of a hopper, an opening through the bottom of the hopper, two alternately-working slides one located above the other, adapted to permit of the delivery of one skewer-blank at a time from the said hopper, a rock-shaft, two levers mounted on the rock-shaft, each lever engaging with its respective slide, an eye in the lower end of each of the said levers, a shaft passing through the eyes, cams mounted on the said shaft operating the said levers, and means for imparting motion to the said shaft, substantially as specified.
